			== HTML5 Canvas Element ==

			Thought you might like to play around with this.. I just stumbeled on this shape hacking a grid together.

			<html>
			<head>
			<title>@title</title>
			<script type="text/javascript">
			function rect(ctx, grid, step, cur){
			ctx.lineTo(cur, 0)
			ctx.lineTo(cur, grid)
			ctx.lineTo(0, cur)
			ctx.lineTo(grid, cur)
			ctx.stroke()
			if (cur < grid){
			rect(ctx, grid, step, cur+step)
			}
			}
			function draw(grid){
			var canvas = document.getElementById('bg');
			if (canvas.getContext){
			var ctx = canvas.getContsext('2d');
			ctx.strokeStyle = '#808080';
			rect(ctx, grid, 20, 20)
			}
			}
			</script>
			<style type="text/css">
			canvas { border: 1px solid black; }
			</style>
			</head>
			<body onload="draw(800);">
